CROSS REFERENCE TO PRIOR APPLICATIONS

The present application claims priority under 35 U.S.C. §119 to Korean Patent Application No. 10-2010-0133723 (filed on Dec. 23, 2010), which is hereby incorporated by reference in its entirety.

FIELD OF THE INVENTION

Apparatuses and methods consistent with the present invention relate to providing a service by sharing solution providing units in a cloud computing environment.

BACKGROUND OF THE INVENTION

Lately, different types of cloud computing services have been introduced. Such a cloud computing service may be provided through virtual machines created in a cloud computing environment. A system may generate different solutions to provide a respective service. The solutions may be results of performing functions to provide the respective service. In order to obtain such solutions, the system may dedicatedly create a virtual machine for each service.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below, in order to explain the present invention by referring to the figures.

Throughout the specification, a service unit may denote a unit that provides a requested service by sharing at least one solution providing unit through a corresponding solution managing unit in a cloud computing environment. The service unit may be a virtual machine created on a cloud computing environment or a hardware computing device coupled to a cloud computing system through a network. The service unit may include a communication unit for communicating with other devices in the cloud computing environment and a control unit for controlling other devices that perform functions required for providing the requested service. A solution may denote a result of performing a corresponding function required for providing a requested service. A solution providing unit may be a unit that provides a requested solution by performing a corresponding function required for providing a requested service. Such a solution providing unit may be a virtual machine created in a corresponding cloud computing environment or a hardware device coupled to a corresponding cloud computing system through a network.

FIG. 1 illustrates a related system for providing a service in a cloud computing environment.

Referring to FIG. 1, the related system 100 may include a plurality of service units and a plurality of solution providing units. For example, the related system 100 may include an image search service unit 110, an augmented reality (AR) service unit 120, an AR advertisement service unit 130, and image recognition solution providing units 112, 122, and 132, an image search solution providing unit 114, AR solution providing units 124 and 134, a content database (DB) 126, and an location based service (LBS)/advertisement solution providing unit 136.

The image search service unit 110 may receive an image search service request and service information from a user equipment 190 and provide the requested image search service. The service information may include information on a target image to search for. Since the image search service unit 110 requires an image search solution and an image recognition solution, the image search service unit 110 may request the image recognition solution providing unit 112 and the image search solution providing unit 114 to perform related functions to generate the image search solution and the image recognition solution. The image recognition solution providing unit 112 may perform an image recognition function based on the service information received from the image search service unit 110. As the image recognition solution, the image recognition solution providing unit 112 may return a result of the image recognition function to the image search service unit 110. The image search solution providing unit 114 may receive the image parameters from the image recognition solution providing unit 112 through the image search service unit 110. The image search solution providing unit 114 may perform an image search function based on the image parameters and return a result of the image search function, as an image search solution, to the image search service unit 110. The image search service unit 110 may provide the image search service to the user equipment 190 based on the image search solution and the image recognition solution received from the image recognition solution providing unit 112 and the image search solution providing unit 114.

The AR service unit 120 may provide an AR service to the user equipment 190. Since the AR service unit 120 may require an image recognition solution and an AR solution, the AR service unit 120 may request the image recognition solution providing unit 112 and the AR solution providing unit 124. The image recognition solution providing unit 112 and the AR solution providing unit 124 may perform corresponding functions and return results of the corresponding functions, as the image recognition solution and the AR solution, to the AR service unit. The AR service unit 120 may receive the image recognition solution and the AR solution and provide the AR service to the user equipment 190.

The AR advertisement service unit 130 may provide an AR advertisement service to the user equipment 190. Since the AR advertisement service unit 130 may require an image recognition solution, an AR solution, and an LBS/advertisement solution, the AR advertisement service unit 130 may request the image recognition solution providing unit 132, the AR solution providing unit 134, and the LBS/advertisement solution providing unit 136 to provide required solutions. The image recognition solution providing unit 132, the AR solution providing unit 134, and the LBS/advertisement solution providing unit 136 may perform corresponding functions and return results of the corresponding functions, as the required solutions, to the AR advertisement service unit 130. The AR advertisement service unit 130 may provide the AR advertisement service based on the image recognition solution, the AR solution, and the LBS/advertisement solution.

As described above, the image search service unit 110, the AR service unit 120, and the AR advertisement service unit 130 may commonly require the image recognition solution for providing the image search service, the AR service, and the AR advertisement service. Each one of the service units 110, 120, and 130, however, uses a dedicated solution providing unit 112, 122, or 132 for the same image recognition solution. Furthermore, the service units 110, 120, and 130 may exchange the same information with corresponding solution providing units 112, 122, and 132 for obtaining the same image recognition solution. Such a manner of using the solution providing unit may waste resources in a cloud computing environment.

Hereinafter, operations of the related system 100 will be described, in detail, with respect to each service. In the case of an image search service, the user equipment 190 may access the image search service unit 110. Since the image search service may require an image recognition solution and an image search solution, the image search service unit 110 may access the image recognition solution providing unit 112 and the image search solution providing unit 114. For example, the image search service unit 110 may receive an image search service request from the user equipment 190. The image search service unit 110 may receive image data input from the user equipment 190 and transmit the received image data to the image recognition solution providing unit 112. The image recognition solution providing unit 112 may extract image parameters from the received image data and transmit the extracted image parameters, as the image recognition solution, to the image search service unit 110. Then, the image search service unit 110 may transmit the received image parameters to the image search solution providing unit 114. The image search solution providing unit 114 may search the content DB 126 and return the search results as the image search solution to the image search service unit 110. The image search service unit 110 may transmit the received search results to the user equipment 190.

In the case of an AR service, the user equipment 190 may access an AR service unit 120. Since the AR service may require an image recognition solution and an AR solution, the AR service unit 120 may access the image recognition solution providing unit 122, the AR solution providing unit 124, and the content DB 126. For example, the AR service unit 120 may receive an AR service request from the user equipment 190. The AR service unit 120 may receive image data from the user equipment 190 and transmit the received image data to the image recognition solution providing unit 122. The image recognition solution providing unit 122 may extract image parameters from the received image data and transmit the extracted image parameters to the AR service unit 120. The AR service unit 120 may search the content DB 126 for contents necessary to provide the requested AR service based on the received image parameters. The AR service unit 120 may transmit the received image data and the searched contents to the AR solution providing unit 124. The AR solution providing unit 124 may combine the received image data and the contents and return the results with control data to the AR service unit 120. The AR service unit 120 may transmit the received results to the user equipment 190.

In the case of an AR advertisement service, the user equipment 190 may access the AR advertisement service unit 130. Since the AR advertisement service unit 130 may require an image recognition solution, an AR solution, and an LBS/advertisement solution, the AR advertisement service unit 130 may access the image recognition solution providing unit 132, the AR solution providing unit 134, and the LBS/advertisement solution providing unit 136. For example, the AR advertisement service unit 130 may receive an AR advertisement service request including location information and image data from the user equipment 190. The AR advertisement service unit 130 may transmit the received image data to the image recognition solution providing unit 132. The image recognition solution providing unit 132 may extract image parameters from the received image data and transmit the extracted image parameters as the image recognition solution to the AR advertisement service unit 130. The AR advertisement service unit 130 may transmit the received image parameters and the received location information to the LBS/advertisement solution providing unit 136. The LBS/advertisement solution providing unit 136 may retrieve advertisement contents based on the location information and the image parameters and transmit the advertisement contents to the AR advertisement service unit 130. The AR advertisement service unit 130 may transmit the received advertisement contents and the received image data to the AR solution providing unit 134. The AR solution providing unit 134 may combine the received image data and the advertisement contents and return the results with control data to the AR advertisement service unit 130. The AR advertisement service unit 130 may transmit the received results to the user equipment 190.

As described above, the service units 110, 120, and 130 may redundantly require the same solution providing units 112, 122, and 132 or 124 and 134 for providing different services requiring the same solution. Such a manner of using the solution providing units may waste resources in a cloud computing environment.

In accordance with an embodiment of the present invention, a system 200 may provide a cloud computing service in a cloud computing environment. Unlike the related system 100 of FIG. 1, the system 200 may share at least one solution providing unit for providing different services requiring the same or similar solutions.

FIG. 2 illustrates a system for providing a service by sharing at least one solution providing unit in a cloud computing environment, in accordance with an embodiment of the present invention.

Referring to FIG. 2, the system 200 may include a plurality of service units 210, 220, and 230 and a plurality of solution managing units 240, 250, 260 and 270. The service units 210, 220, and 230 and the solution managing units 240, 250, 260 and 270 may each be a virtual machine created in a cloud computing environment according to user demand, but the present invention is not limited thereto. The service units 210, 220, and 230 and the solution managing units 240, 250, 260 and 270 may be hardware computing devices coupled to a cloud computing system through a network. The system 200 may further include a content database (DB) 222.

The service units 210, 220, and 230 may receive service requests from a plurality of user equipments and provide the requested services to the plurality of user equipments by sharing at least one solution providing unit generating a same solution for different services through a related solution managing unit. For example, a user equipment 290 may transmit a service request for a desired service to one of the service units 210, 220, and 230. When the user equipment 290 transmits the service request, the user equipment 290 may transmit service information with the service request. The service information may be information necessary for using the desired service. The service information may include image data and Internet protocol (IP) addresses of a user equipment and a service unit. In the case of the image search service, the service information may include an image data. The user equipment 290 may store such an image data, or receive the image data from another device through a network. Furthermore, the user equipment 290 may capture a target image using a camera module and transmit the captured image to the at least one service unit as the service information.

Particularly, the system 200 may include an image search service unit 210, an AR service unit 220, and an AR advertisement service unit 230, but the present invention is not limited thereto. The image search service unit 210, the AR service unit 220, and the AR advertisement service unit 230 may have a similar configuration and perform similar functions as compared to the image search service unit 110, the AR service unit 120, and the AR advertisement service unit 130 of FIG. 1. Accordingly, more detailed descriptions thereof will be omitted here. The image search service unit 210, the AR service unit 220, and the AR advertisement service unit 230 will be described based on distinguishing functions and configurations.

As described above, the image search service unit 210 may provide an image search service to a plurality of user equipments. The AR service unit 220 may provide an AR service and the AR advertisement service unit 230 may provide an AR advertisement service to a plurality of user equipments such as the user equipment 290. The image search service, the AR service, and the AR advertisement service may require a same solution such as an image recognition solution and an AR solution. Accordingly, the image search service unit 210, the AR service unit 220, and the AR advertisement service unit 230 may share an image recognition solution providing unit 252 and an AR solution providing unit 262. That is, the image recognition solution providing unit 252 and the AR solution providing unit 262 may be commonly used by the image search service unit 210, the AR service unit 220, and the AR advertisement service unit 230 through an image recognition solution managing unit 250 and an AR solution managing unit 260.

In order to share at least one solution providing unit, each one of the image search service unit 210, the AR service unit 220, and the AR advertisement service unit 230 may determine which solutions are required to provide the requested services. Based on the determined solutions, each one of the image search service unit 210, the AR service unit 220, and the AR advertisement service unit 230 may select required solution managing units. Then, each one of the image search service unit 210, the AR service unit 220, and the AR advertisement service unit 230 may transmit a solution request and the service information to the selected solution managing units. Thereafter, each one of the image search service unit 210, the AR service unit 220, and the AR advertisement service unit 230 may receive the requested solutions from the selected solution managing units. Each one of the image search service unit 210, the AR service unit 220, and the AR advertisement service unit 230 may process the received solutions and provide the requested service to the plurality of user equipments, for example, to the user equipment 290.

In accordance with an embodiment of the present invention, the system 200 may further include an image search solution managing unit 240, an image recognition solution managing unit 250, an AR solution managing unit 260, and an LBS/advertisement solution managing unit 270. As described above, each one of the image recognition solution managing unit 250, the AR solution managing unit 260, and the LBS/advertisement solution managing unit 270 may receive solution requests from the service units 210, 220, and 230. Each one of the image recognition solution managing unit 250, the AR solution managing unit 260, and the LBS/advertisement solution managing unit 270 may provide the requested solutions to the service units 210, 220, and 230 by sharing at least one solution providing unit generating a same solution required for different services. That is, at least one solution providing unit may be commonly used to provide different services. In accordance with an embodiment of the present invention, the system 200 does not use a dedicated solution providing unit for each service unit.

In order to share one of the solution providing units, each one of the image recognition solution managing unit 250, the AR solution managing unit 260, and the LBS/advertisement solution managing unit 270 may manage corresponding solution providing units according to a service demand. For example, each one of the image recognition solution managing unit 250, the AR solution managing unit 260, and the LBS/advertisement solution managing unit 270 may select a corresponding solution providing unit based on processing loads of each solution providing unit. Furthermore, each one of the image recognition solution managing unit 250, the AR solution managing unit 260, and the LBS/advertisement solution managing unit 270 may select a corresponding solution providing unit based on locations thereof when the solution providing units are hardware computing devices coupled to the system 200. Alternatively, the solution managing units 240, 250, 260, and 270 may create a solution providing unit when there is no existing solution providing unit or when every solution providing unit exceeds a certain processing load.

The image search solution managing unit 240 may manage at least one image search solution providing unit 242. The image search solution providing unit 242 may be a virtual machine created to perform an image search function. As described above, the image search solution managing unit 240 may dynamically manage image search solution providing units according to a service demand. For example, the image search solution managing unit 240 may select an existing image search solution providing unit or create a new image search solution providing unit according to service demands of the service units. For example, the image search solution managing unit 240 may receive multiple requests from a plurality of different service units for providing different types of services requiring the same solution, for example, an image search solution. In this case, the image search solution managing unit 240 may provide image search solutions by sharing at least one image search solution providing unit 242.

The image recognition solution managing unit 250 may manage at least one image recognition solution providing units 252, 254, and 256. The image recognition solution providing units 252, 254, and 256 may each be a virtual machine created to perform an image recognition function. As described above, the image recognition solution managing unit 250 may dynamically manage the image recognition solution providing units 252, 254, and 256 according to a service demand. For example, the image recognition solution managing unit 250 may select one of existing image recognition solution providing units 252, 254, and 256 or create a new image recognition solution providing unit according to service demands of the service units. For example, the image recognition solution managing unit 250 may receive multiple requests from a plurality of different service units 210, 220, and 230 for providing different services requiring the same solution. The image recognition solution managing unit 250 may provide the same solution such as an image recognition solution for the image search service, the AR service, and the AR advertisement service. In this case, the image recognition solution managing unit 250 may share at least one of the image recognition solution providing units 252, 254, and 256 for providing the image recognition solution.

The AR solution managing unit 260 may manage at least one of the AR solution providing units 262 and 264. The AR solution providing units 262 and 264 may each be a virtual machine created to perform an AR function for generating an AR solution. As described above, the AR solution managing unit 260 may dynamically manage the AR solution providing units 262 and 264 according to a service demand. For example, the AR solution managing unit 260 may select one of existing AR solution providing units 262 and 264 or create a new AR solution providing unit according to service demands of the service units. For example, the AR solution managing unit 260 may receive multiple requests from a plurality of different service units 220 and 230 for providing different services, for example, the AR service and the AR advertisement service. In this case, the AR solution managing unit 260 may share at least one of the AR solution providing units 262 and 264 for providing the AR solution.

The LBS/advertisement solution managing unit 270 may manage at least one LBS/advertisement solution providing unit 272. The LBS/advertisement solution providing unit 272 may be a virtual machine created to perform an LBS/advertisement function that generates an LBS/advertisement solution. The LBS/advertisement solution may be advertisement contents selected from the content DB 222 based on a current location of the user equipment 290. As described above, the LBS/advertisement solution managing unit 270 may dynamically manage the LBS/advertisement solution providing unit 272 according to a service demand. For example, the LBS/advertisement solution managing unit 270 may select the existing LBS/advertisement solution providing unit 272 or create a new LBS/advertisement solution providing unit according to service demands of the service units. For example, the LBS/advertisement solution managing unit 270 may receive multiple requests from a plurality of different service units for providing different services requiring at least one same solution. In this case, the LBS/advertisement solution managing unit 270 may provide LBS/advertisement solutions by sharing at least one LBS/advertisement solution providing unit 272.

Hereinafter, operations of the image recognition solution managing unit 250, the AR solution managing unit 260, and the LBS/advertisement solution managing unit 270 will be described in more detail. In the case of an image search service, the image search solution managing unit 240 and the image recognition solution managing unit 250 may receive the solution requests from the image search service unit 210 with the target image data which is received from the user equipment 290. Each one of the image search solution managing unit 240 and the image recognition solution managing unit 250 may select one of corresponding solution providing units based on processing loads of each solution providing unit. The image search solution managing unit 240 and the image recognition solution managing unit 250 may transmit a solution request and the service information to the selected solution providing units, respectively. The image search solution managing unit 240 and the image recognition solution managing unit 250 may receive solutions from the selected solution providing units, respectively. The solutions may be a result of performing the requested functions at the selected solution providing units. The image search solution managing unit 240 and the image recognition solution managing unit 250 process the received solutions and provide the processing results to a corresponding service unit.

When an AR service is requested to the AR service unit 220, the image recognition solution managing unit 250 and the AR solution managing unit 260 may be selected to provide the AR service solution to the AR service unit 220. When an AR advertisement service is requested to the AR advertisement service unit 230, the image recognition solution managing unit 250, the AR solution managing unit 250, and the LBS/advertisement solution managing unit 270 may be selected to provide the AR advertisement solution to the AR advertisement service unit 230. The AR advertisement solution may be advertisement contents with control data. A user equipment may control output devices in response to the control data. For example, a vibration module of a user equipment may be vibrated for a certain time period in response to the control data.

As described above, different types of services requiring at least one same solution may be provided by sharing at least one solution providing unit through a corresponding solution managing unit. For example, the image recognition solution providing unit 252 may be commonly used to provide the image search service, the AR service, and the AR advertisement service.

Accordingly, the system 200 in accordance with an embodiment of the present invention may effectively utilize cloud computing resources to provide the requested service in a cloud computing environment.

Hereinafter, a method for providing a service by sharing at least one solution providing unit through solution managing units, in accordance with an embodiment of the present invention, will be described with reference to FIG. 3.

FIG. 3 illustrates a method for providing a service by sharing at least one solution providing unit in a cloud computing environment, in accordance with an embodiment of the present invention.

Referring to FIG. 3, a request for a desired service may be transmitted with service information to at least one service unit S310. For example, the user equipment 290 may transmit a request for a desired service to one of the service units 210, 220, and 230. In the case of an image search service, the user equipment 290 may transmit a request for the image search service to the image search unit 210. When the user equipment 290 transmits the request, the user equipment 290 may transmit a target image data as the service information. The target image data may be received from a user through a network and stored in the user equipment 290. Alternatively, the target image data may be captured using a camera module of the user equipment 290, but the present invention is not limited thereto.

The request and the service information may be received S320. For example, the image search service unit 210 may receive the request and the target image data as the service information from the user equipment 290. Then, solutions required for the requested service may be determined based on the request and the service information S330. For example, the image search unit 210 may determine which solutions are required to provide the image search service. In this case, the image search unit 210 may determine that an image recognition solution and an image search solution are required for the image search service.

At least one solution managing unit may be selected based on the required solutions S340. For example, the image search unit 210 may select the image search solution managing unit 240 and the image recognition solution managing unit 250 based on the required solutions, for example, the image recognition solution and the image search solution.

The request and the service information may be transmitted to the at least one selected solution managing unit S350. For example, the image search service unit 210 may transmit the request and the service information to the image search solution managing unit 240 and the image recognition solution managing unit 250, but the present invention is not limited thereto. The image search service unit 210 may transmit a request and image parameters to the image search solution managing unit 240 after receiving the image parameters from the image recognition solution managing unit 250 as a result of the image recognition solution.

A solution providing unit may be selected and a solution request and the service information may be transmitted to the selected solution providing unit S360. For example, the image search solution managing unit 240 may select the image search solution providing unit 242 and transmit a solution request and the service information received from the user equipment 290 to the image search solution providing unit 242. The image recognition solution managing unit 250 may select one of the image recognition solution providing units 252, 254, and 256 based on a processing load of each image recognition solution providing unit. After selection, the image recognition solution managing unit 250 may transmit a solution request and the service information. The present invention, however, is not limited thereto. The solution managing unit may create a new corresponding solution providing unit.

A required function may be performed and a result of performing the function may be returned to a corresponding solution managing unit S370. For example, the image recognition solution providing unit 252 may perform an image recognition function based on the service information, for example, the target image data, and return image parameters as the result of performing the image recognition function to the image recognition solution managing unit 250. The result of performing the image recognition function may be the image recognition solution. The image recognition solution managing unit 250 may transmit the result of the image recognition function to the image search solution managing unit 240 through the image search service unit 210 or directly to the image search solution managing unit 240. Furthermore, the image search solution providing unit 242 may perform the image search function based on the image parameter received from the image recognition solution managing unit 250. After performing the image search function, the image search solution providing unit 242 may return a result of the image search function, as a solution, to the image search solution managing unit 240.

The solution may be delivered to the corresponding service unit S380. For example, the image search solution managing unit 240 and the image recognition solution managing unit 250 may return the solutions received from the image search solution providing unit 242 and the image recognition solution managing unit 250 to the image search service unit 210.

At least one solution received from the at least one determined solution managing unit may be processed and the requested service may be provided to the user equipment based on the solution processing result S390. For example, the image search service unit 210 may process the solutions from the image search solution managing unit 240 and the image recognition solution managing unit 250 and provide the requested image search service to the user equipment 290.
